CEILING-PIIAATE.

y Be a known that 1 ALBERT L. seams, acumen or the United States, and a resident of Bristol, in the; county of Hartford and State of Connecticut, have inventeda neivg'an'd Improved Ceiling-Plate, of which the following is a specification. 7

My invention relates to the class-of devices employed for covering an opening between a pipe and Wall or ceiling through which opening the pipe passes to provide-a finish, and an object of my invention, among is to provide a device of this class in Which the sections have improved fastening means forsecuring them in place. fOne form of devic'e embodying/my invention and in the construction and use of Whichthe o b ect herein-set out, asivell as others,may be 20 attained is illustrated in the accompanying drawings in Which' Figure 1 is a plan "view of'as'ectional ceilplate embodying my invention, the sections being shown separated. H p

Fig. 2 is a View insectionthlough a ivall or ceiling and in elevation of abroken sec tion of pipe showing iny improved ceiling plate in place, parts of the plate being broken away toshowconstruction. A

Fig. 3 is a detail View showing the sections of the plate in unlocked engagement, the positionof the outer surface of the pipe being denoted by dotted lines. n

Fig. & is a View shoirving a modified form of the invention. I v p p In the accompanying drawings the nu} incral 6 denotes, in general, a Wall or ceiling having an opening-'7 for "a pipe 8 My ini} proved ceiling plate consists of two sections 9 preferably formed of sheet metal struck to shape, and having spring fingers,'to be I term the under surface or the plate, this under surface being that surface located ceiling when the plate against the ivall or is in position.

The sections of the plate are duplicates each of the other, each having an overturned flap 10 located Within a flange 11, each section being semicircular in form and the flaps being supplied from metal taken from Within the semicircle. Each flap is located at such distance from the base of the plate as to provide a socket 12 into which a tongue 13 from the opposite plate projects. A rib 14 may be formed at the base of each flap.

A locking slot 15 is formed in the side of or the plate, thislocking'stud being located cause the. lo k ng sep ra on ,o

1 1; tongue to reeeive a locking stud: 16 upturned from tlieedge o'ftlie opposite" section at oiie side of the socket that receives the tongue V Inassembling the device the tongues are inserted in'thj'eir respective sockets and the two sections of th plate ferced together until their edges meet, and then a radial movement of the section'sonenponthe other the locking studs are causedt tov engage the 7 locking slots and thus preventseparatioii of the plate, H v y 1 In, order to retain the sections in the loqked'engagemefit justdescribedthe leek ing fingers 17 are s'oflooated that their-pressure upon the pipe w'ill be in a dircction' to studs to be retained "within the locking, slots, in the construction herein shown-the locking slots being located on the outer edge'of the ,ton'gue The fingers I? are each located'on that edge of 'itssection abutting against the edge of the o positesection having the o'verti'lriiec'l flap. It Will be iun cler'stood matte fingers are s'u'fliciently resilient toi enable the sections 'to' be moved radially underfproper force todisenga'ge the locking, stud fro injthe locking slot. Another "set 18 of spring fingers are located preferably m'iaw y between the fingers 17 to as sist 'inj'positioningthe plate. a

Injthe form'of the'device shown in Fig. 4

a rib 20 is formed on one 'o'r both of the tongues, 'tihisrib engaging frecessjl" in the under surface of the overturned flap. The

rib and recess are so inclinedjth'at as the 'ttv'osjections of the plate are forc'e d together they will al'sobe forced'i'n radial direction to v cause the locking stud to engage the l'oeking slot. I

. I i ind de' a a invention'that positive lock for preventing the sections shall exist andin fact construction herein sho'tvn maybe "changed to a greater or lesser extent and yet embody the invention.

lVhile there has been shown and described herein fingers Which resiliently grasp the pipe it will be understood that any means for obtaining this pressure against the pipe may be employed, and I'do not therefore limit the structure to this resilient featureas contained in the spring fingers alone.

I claim- 3 1. A ceiling plate including two sections arranged'to encircle a pipe,- each of the sec em jit ssential to'the loo 7 tions having a flap overturned fro1nits inner edge near its end, a stud projecting from the end of each section at a point opposite the bend of said flap, and a projecting tongue from the end of each section near its inner edge positioned to pass between the curved overturned edge of the flap and said stud.

2. A ceiling plate including two sections of semicircular form arranged to encircle a pipe, said sections having flaps bent in opposite directions -from opposite inner edges near the ends thereof, said flaps extending toward the outer edge of each section, and a tongue projecting from the end of each section near the inner edge thereof in position to pass underneath said overturned flaps and limit relative lateral 1110661118111) of said sections by engagement with the bent edges of said flaps.

3. A ceiling plate including two sections arranged to encircle a pipe, one of the sections having an overturned flap forming a recess, a tongue on the opposite section arranged to pass into said recess and having a locking notch, and a stud upon the opposite section arranged to engage said notch to hold the sections in locked engagement.

4. A ceiling plate including two sections arranged to encircle a pipe, one of the sections having an overturned resilient fiap forming a recess, a tongue on the opposite section arranged to pass into said recess, said tongue having a locking notch, a looking stud arranged to engage said notch, and means upon the sections to resiliently hold the parts in locked engagement.

5. A ceiling plate including two sections arranged to encircle a pipe, one of the sections having an overturned flap forming a recess, a tongue upon the other section located to pass into said recess, said tongue having a locking slot, a locking stud upon the, opposite section arranged to engage the locking slot, and a spring finger positioned upon the sections to oppose movement of the sections to disengage said stud "from said slot. I v

'G. A ceiling plate including two sections arranged to encircle a pipe, each of the sectionshaving on one end an overturned flap Copies of this patent may beobtained for five cents each, by addressing the forming a recess and a tongue projecting from the opposite end to engage a recess formed by a flap, each tongue having a locking slot, a stud to engage said locking slot, and spring fingers projecting from each of the sections and located to yieldingly resist movement of the sections to disengage the studs from the slots.

7 A ceiling plate including two sections arranged to encircle a pipe, each of the sections having on one end a loop open on one side, a tongue projecting from the opposite end of each section to engage a loop on the opposite section and spring fingers projecting from each of the sections and located to yieldingly resist movement of the sections in a direction to move a tongue out of the open side of its engaging loop.

8. A ceiling plate including two sections arranged to encircle a pipe, one of? the sections having a flap overturned. from the metal originally composing the center of the plate and forming a recess and the other a tongue arranged to pass into said recess and limit relative lateral movement of said sections by engagement with the bent edges of said flaps, meansupon the sections for holding them in locked engagement, and means for resiliently resisting movement of the sections to unlock them.

9. A ceiling plate including two sections duplicates each of the other and each having a socket at one end and a tongue at the other end arranged to pass into said socket and therebylimit the lateral movement of the sections one with respect to the other, and means for holding the sections in locked engagement.

10. A ceiling plate including two sections duplicates each of the other and each having at one end a socket formed by a flap overturned from the metal originally composing the center of the plate and the opposite end of each sectionhaving a tongue adapted to enter the socket formed by said overturned flap and thereby limit the lateral movement of the sections one with respect to the other.
